Reasons behind why you Chose them/Comments (optional):
Xaldin-He was the only boss that I had to use King Mickey for when I fought him in proud mode (Sepheroth, of course, was a pain too, but it didn't feel right putting a final fantasy character in here)
Sora-He pwn'd everybody. The only reason he's second is because I had to use the King like five times when killing Xaldin, so Sora wouldn't have stood a chance on his own.
Roxas-He beat Riku, and put up a better fight against Sora than most of the bosses do when I fight. Also, he can use two keyblades with no party (it's kind of a drawback for Sora at the end. If I could have used my Final Form, Xemnas wouldn't have lasted half as long)
Riku- He's Riku. He's probably the best ally I had, and he was a pain in the first game.
Demyx- water clones. He's hard to beat even WITH reaction commands. Everyone else would be screwed.
